ADVANCEMENT OF A TUBULAR STRING INTO A WELLBORE |
摘要 |
A system can include an annular restrictor connected in a tubular string. The annular restrictor restricts flow through an annulus formed between the tubular string and a wellbore. Restriction to the flow through the annulus biases the tubular string into the wellbore, and fluid in the wellbore displaces into the tubular string and/or a formation penetrated by the wellbore. A method can include connecting an annular restrictor in a tubular string, and flowing a fluid through an annulus formed between the tubular string and a wellbore, thereby causing a differential pressure across the annular restrictor, the differential pressure biasing the tubular string into the wellbore. Another method can include connecting an annular restrictor in a tubular string, flowing a fluid through an annulus, thereby biasing the tubular string into a wellbore, and then causing the annular restrictor to no longer restrict flow through the annulus. |
